-**station_group** describes which **bike_group** are allowed at the station.
+**station_type** describes which **bike_group** are allowed at the station.
 Groups are identified by ID. The following groups of bicycles are defined:
 | Defined group ID's | bike type |
 | ------ | ------ |
-| 300101 | Cargobike |
-| 300103 | Citybike |
+| 300101 | cargo |
+| 300103 | city |
 Keep in mind, each ID is preceded by an operator-prefix. Datatype is array, because each station can have more byke_group
